BACKGROUND

1. Technical Field

The invention relates to a panel, and more particularly, to a displaypanel.

2. Related Art

Thin film transistors are often utilized as a switching element of apixel structure in a display panel. In the known thin film transistorstructure, a gate and a source of the thin film transistor structure areconstituted of different films, and are overlapped with each other incertain region, therefore, a gate-source parasitic capacitance C_(gs)exists between the two electrodes. Similarly, a gate and a drain of thethin film transistor structure are constituted of different films, andare also overlapped with each other in certain region, therefore, agate-drain parasitic capacitance C_(gd) exists between the twoelectrodes. The existence of these parasitic capacitances may affect theelement properties of the thin film transistor structure, therebyaffecting the display quality of the display panel.

According to the above description, thin film transistors are usuallyfabricated in an array. Among the current thin film transistor arrayprocesses, the majorities are employed with adjoined photomasks of astepper exposure machine to perform an exposure process for fabricatingthin film transistor arrays. Therefore, in the exposure process, thedisplacement offsets resulting from movements of the machine would causenonconformity among the pattern locations formed in each exposure shot.When such offset occurs, the overlapping region of the gate and thesource or the overlapping region of the gate and the drain may bedifferent from the predetermined size. At this moment, the thin filmtransistors in the different exposure shots may have different parasiticcapacitances C_(gs) and C_(gd), thereby causing nonconformity to theproperties of thin film transistor, and thus the uneven brightness issueon the whole display panel is occurred during displaying.

DESCRIPTION OF THE EMBODIMENTS

The following individual drawings have adjusted the proportion of everyelement, so that each individual element may be presented distinctly. Assuch, the size of every element is not illustrated with the actualproportion. In addition, the following drawings, in some parts, may onlyillustrate some elements in the display panel for simplifying drawings.

FIG. 1 is a schematic top view illustrating a display panel according toa first embodiment of the invention. Referring to FIG. 1, the displaypanel 100 includes a plurality of scan lines SL, a plurality of datalines DL, a plurality of power lines PL, a plurality of light emittingunits 110, a plurality of first pixel circuits 120 and a plurality ofsecond pixel circuits 130. The light emitting units 110 are arranged inan array. The first pixel circuits 120 are connected to thecorresponding scan lines SL, data lines DL and power lines PL,furthermore, some parts of the light emitting units 110 are connected tothe first pixel circuits 120. The second pixel circuits 130 areconnected to the corresponding scan lines SL, data lines DL and powerlines PL, furthermore, the rest of the light emitting units 110 areconnected to the second pixel circuits 130.

The display panel 100 is substantially employed with two kinds of pixelcircuit 120 and 130 to drive the light emitting units 110. Furthermore,the first pixel circuits 120 and the second pixel circuits 130, here,are formed in different rows. In other words, when the first pixelcircuits 120 are configured to drive the light emitting units 110 on oddrows, the second pixel circuits 130 are configured to drive the lightemitting units 110 on even rows, or when the first pixel circuits 120are configured to drive the light emitting units 110 on the even rows,the second pixel circuits 130 are configured to drive the light emittingunits 110 on odd rows. Moreover, in the embodiment, the (2N)^(th) scanlines SL, for example, may be selectively connected with the (2N−1)^(th)scan lines, such that the first pixel circuits 120 and the second pixelcircuits 130 on the two adjacent rows are controlled by the same scansignal.

FIG. 2 is a circuit diagram illustrating a first pixel circuit inFIG. 1. Referring to FIG. 1 and FIG. 2 together, the first pixel circuit120 includes a first driving transistor 121, a first control transistor122 and a first storage capacitor 123. The first driving transistor 121has a first terminal 121 a, a second terminal 121 b and a third terminal121 c. The first terminal 121 a of the first driving transistor 121 isconnected to one of the power lines PL, and the second terminal 121 b ofthe first driving transistor 121 is connected to one of the lightemitting units 110. The first control transistor 122 has a firstterminal 122 a, a second terminal 122 b and a third terminal 122 c. Thefirst terminal 122 a of the first control transistor 122 is connected toone of the data lines DL, the second terminal 122 b of the first controltransistor 122 is connected to the third terminal 121 c of the firstdriving transistor 121, and the third terminal 122 c of the firstcontrol transistor 122 is connected to one of the scan lines SL. Aterminal 123 a of the first storage capacitor 123 is connected to thethird terminal 121 c of the first driving transistor 121 and the secondterminal 122 b of the first control transistor 122. In an embodiment,the first control transistor 122 and the first driving transistor 121may be N-type transistors. At this moment, another terminal 123 b of thefirst storage capacitor 123 may be connected between the second terminal121 b of the first driving transistor 121 and the light emitting unit110.

FIG. 3 is a circuit diagram illustrating a second pixel circuit inFIG. 1. In the embodiment, the circuit design of the second pixelcircuit 130 is substantially the same as the first pixel circuit 120.Referring to FIG. 1 and FIG. 3, the second pixel circuit 130 includes asecond driving transistor 131, a second control transistor 132 and asecond storage capacitor 133. The second driving transistor 131 has afirst terminal 131 a, a second terminal 131 b and a third terminal 131c. The first terminal 131 a of the second driving transistor 131 isconnected to one of the power lines PL, and the second terminal 131 b ofthe second driving transistor 131 is connected to one of the lightemitting units 110. The second control transistor 132 has a firstterminal 132 a, a second terminal 132 b and a third terminal 132 c. Thefirst terminal 132 a of the second control transistor 132 is connectedto one of the data lines DL, the second terminal 132 b of the secondcontrol transistor 132 is connected to the third terminal 131 c of thesecond driving transistor 131, and the third terminal 132 c of thesecond control transistor 132 is connected to one of the scan lines SL.A terminal 133 a of the second storage capacitor 133 is connected to thethird terminal 131 c of the second driving transistor 131 and the secondterminal 132 b of the second control transistor 132. In an embodiment,the second control transistor 132 and the second driving transistor 131may be N-type transistors. At this moment, the second terminal 133 b ofthe second storage capacitor 133 may be connected between the secondterminal 131 b of the second driving transistor 131 and the lightemitting unit 110.

In the first pixel circuit 120, when the first control transistor 122 isturned on, a data voltage transmitted through the data line DL isapplied on the third terminal 121 c of the first driving transistor 121.When the first control transistor 122 is turned off, the data voltageapplied on the third terminal 121 c of the first driving transistor 121is maintained by the first storage capacitor 123. At this moment, theturn-on of the first driving transistor 121 may control the drivingcurrent flowing through the light emitting unit 110 from the power linePL. Therefore, under such design of driving circuit, the turn-on orturn-off of the first control transistor 122 has the function ofcontrolling the data voltage to write into, while the turn-on orturn-off of the first driving transistor 121 has the function ofcontrolling the driving current. In addition, in the second pixelcircuit 130, the functions of the second control transistor 132 and thesecond driving transistor 131 are similar to the first controltransistor 122 and the first driving transistor 121 in the first pixelcircuit 120 described above, therefore will not be described againherein.

In the embodiment, the driving circuit with the framework of twotransistors and a capacitor (2T1C) is exemplified to describe the firstpixel circuit 120 and the second pixel circuit 130, however, theinvention is not limited to the coupling method and the amount oftransistors and capacitors in the pixel circuits. The designer maymodify the coupling method and the amount of transistors and capacitorsin the pixel circuits according to the actual application requirement,such as modifying to a pixel circuit with the framework of fourtransistors and two capacitors (4T2C) to drive the light emitting units.At this moment, the pixel circuit with the framework of four transistorsand two capacitors, other than having the similar data lines, scanlines, power lines, capacitors, control transistors and drivingtransistors in the first pixel circuit 120 and the second pixel circuit130, may also selectively have other elements 140 (as illustrated inFIG. 1). In other words, the connection relationship and the structuraldesign for these elements (namely, the data lines, the scan lines, thepower lines, the capacitors, the control transistors and the drivingtransistors etc.) described in the embodiment may be utilized in thedriving circuit with the framework of 4T2C or other frameworks.

Referring to FIG. 1, in the embodiment, the first terminal 122 a and thesecond terminal 122 b of the first control transistor 122 and the firstterminal 132 a and the second terminal 132 b of the second controltransistor 132 are constituted of the same film. Namely, the firstterminals 122 a, 132 a and the second terminals 122 b, 132 b arefabricated in the same exposure process during the manufacturing processof the display panel 100. Moreover, the third terminal 122 c of thefirst control transistor 122 and the third terminal 132 c of the secondcontrol transistor 132 are fabricated with the same film, but the filmlayer of the third terminals 122 c, 132 c is different from the filmlayer of the aforementioned first terminals 122 a, 132 a and secondterminals 122 b, 132 b. Therefore, in the exposure process offabricating the first control transistor 122 and the second controltransistor 132, the displacement offset of the photomasks may cause therelative locations of the third terminals 122 c, 132 c and the firstterminals 122 a, 132 a different from the predetermined locations.Similarly, the relative locations of the third terminals 122 c, 132 cand the second terminals 122 b, 132 b may also have such offset.

In each of the first pixel circuits 120, the first terminal 122 a andthe second terminal 122 b of the first control transistor 122 aresequentially arranged on a forward direction of a first direction D asshown as the arrow. In each of the second pixel circuits 130, the firstterminal 132 a and the second terminal 132 b of the second controltransistor 132 are sequentially arranged on a reverse direction of thefirst direction D. In the embodiment, the first direction D is, forexample, defined as the main data transmission direction that the firstcontrol transistor 122 of the first pixel circuit 120 transmits the datafrom the data lines DL.

In other words, in the embodiment, the forward direction of the firstdirection D is defined as the first terminal 122 a is relatively locatedabove the second terminal 122 b and the first terminal 132 a isrelatively located below the second terminal 132 b when the direction isfrom the top to the bottom of FIG. 1. During the manufacturing process,when the second terminal 122 b of the first control transistor 122 isdeviated from a predetermined location towards the forward direction ofthe first direction D in relative to the third terminal 122 c, thelocation of the second terminal 122 b may be away from the centre of thethird terminal 122 c in relative to the predetermined location. When thesecond terminal 132 b of the second control transistor 132 is alsodeviated from a predetermined location towards the forward direction ofthe first direction D in relative to the third terminal 132 c, thelocation of the second terminal 132 b may be further close to the centreof the third terminal 132 c in relative to the predetermined location.

At this moment, the overlapping area between the second terminal 122 band the third terminal 122 c of the first control transistor 122 may bereduced in relative to the predetermined design, while the overlappingare between the second terminal 132 b and the third terminal 132 c ofthe second control transistor 132 may be increased in relative to thepredetermined design. Accordingly, the parasitic capacitance between thesecond terminal 122 b and the third terminal 122 c of the first controltransistor 122 and the parasitic capacitance between the second terminal132 b and the third terminal 132 c of the second control transistor 132may be compensated with each other. Similarly, the parasitic capacitancebetween the first terminal 122 a and the third terminal 122 c of thefirst control transistor 122 and the parasitic capacitance between thefirst terminal 132 a and the third terminal 132 c of the second controltransistor 132 may be compensated with each other.

The first terminal 122 a and the second terminal 122 b of the firstcontrol transistor 122 are sequentially arranged on the forwarddirection of the first direction D in the first pixel circuit 120, andthe first terminal 132 a and the second terminal 132 b of the secondcontrol transistor 132 are sequentially arranged on the reversedirection of the first direction D in the second pixel circuit 130.Therefore, when the offset occurs, the deviated locations in relative tothe locations of every component in the first control transistor 122 andthe second control transistor 132 may be compensated with each other. Atthis moment, the element properties of the first control transistor 122and the second control transistor 132 may be changed in a reverse way.

For example, once the offset occurs, the light emitting units 110 drivenby the first pixel circuits 120 appears to increase the brightness inrelative to the predetermined brightness, while the light emitting units110 driven by the second pixel circuits 130 may appear to decrease thebrightness in relative to the predetermined brightness. In this way,when the light emitting units 110 with the same color are driven by boththe first pixel circuits 120 and the second pixel circuits 130, thedisplay brightness of this color in the entire display panel 100 may becompensated with each other, thereby achieving the ideal displayuniformity. It should be mentioned that, the first direction D in theembodiment is exemplified by the extending direction parallel to thedata lines DL to describe herein. However, in other embodiments, thefirst direction D may be assigned to be the direction that thedisplacement offset is relatively easy to occur or the direction thatthe displacement offset is greater degree in the exposure process.Moreover, the following description may be incorporated with theaccompanying drawings to further describe the layout design of thedisplay panel 100 in the embodiment.

FIG. 4 is a layout diagram illustrating a display panel in FIG. 1,wherein FIG. 4 only illustrates the pixels circuits and the lightemitting units schematically. Referring to FIG. 4, the plurality oflight emitting units 110 on the display panel 100 are adapted to displaya variety of different colors. In the embodiment, the light emittingunits 110 appearing in four colors (such as red, green, blue and white)are exemplified. In other words, the light emitting units 110 areexemplified by including the four types such as the red light emittingunit 110 a, the green light emitting unit 110 b, the blue light emittingunit 110 c and the white light emitting unit 110 d to describe herein.However, in other embodiments, the colors displayed by the lightemitting units 110 may only selectively include three different colors.Moreover, other than the primary colors of red, green and blue (RGB)described above, in other embodiments, the colors displayed by the lightemitting units 110 may include the primary colors of magenta, cyan, andyellow or other combinations of different colors.

In the light emitting units 110 with the same color of the display panel100, some parts of the light emitting units 110 are connected to thefirst pixel circuits 120, and other parts are connected to the secondpixel circuits 130. Thus, once the displacement occurs in themanufacturing process, the display effect of the display panel 100 isobtained the self-compensation effect. For example, in FIG. 4, the firstpixel circuits 120 on the same row sequentially includes the first pixelcircuits 120A, the first pixel circuits 120B, the first pixel circuit120C and the first pixel circuits 120D. The second pixel circuits 130 onthe same row sequentially include the second pixel circuits 130A, thesecond pixel circuits 130B, the second pixel circuits 103C and thesecond pixel circuits 130D. At this moment, among the light emittingunits 110 on the two adjacent rows, the red light emitting units 110 aon one row are connected with the first pixel circuits 120A, while thered light emitting units 110 a on the other row are connected with thesecond pixel circuits 130C. Likewise, the green light emitting units 110b on one row are connected with the first pixel circuits 120C, while thegreen light emitting units 110 b on the other row are connected with thesecond pixel circuits 130A. The blue light emitting units 110 c on oneof the rows are connected with the first pixel circuits 120D, while theblue light emitting units 110 c on the other row are connected with thesecond pixel circuits 130B. The white light emitting units 110 d on oneof the rows are connected with the first pixel circuits 120B, while thewhite light emitting units 110 d on the other row are connected with thesecond pixel circuits 130D.

To be specific, in the embodiment, one of the red light emitting units110 a is connected with the first pixel circuit 120A, while another oneof the red light emitting units 110 a is connected with the second pixelcircuit 130C. According to FIG. 1, the first terminal 122 a and thesecond terminal 122 b of the first control transistor 122 aresequentially arranged on the forward direction of the first direction Din the first pixel circuits 120, and the first terminal 132 a and thesecond terminal 132 b of the second control transistor 132 aresequentially arranged on the reverse direction of the first direction Din the second pixel circuits 130. In this way, it is assumed that whensome parts of the red light emitting units 110 a connected with thefirst pixel circuits 120 become brighter due to the parasiticcapacitance, the other parts of the red light emitting units 110 aconnected with the second pixel circuits 130 may become darker, suchthat both parts may have the effect of compensating with each other.Similarly, among the plurality of green light emitting units 110 b, bluelight emitting units 110 c and white light emitting units 110 d, thelight emitting units 110 with the same color have some parts connectingwith the first pixel circuits 120 and other parts connecting to thesecond pixel circuits 130. Therefore, the plurality of light emittingunits 110 with the same color may also have the same compensation effectas the aforementioned red light emitting units 110 a, so that thedisplay panel 100 has the fine display quality.

Referring to FIG. 4, in the embodiment, the two adjacent light emittingunits 110 on the same row are the light emitting units 110 displayingdifferent colors. In addition, the light emitting units 110 on each rowinclude the light emitting units 110 with all the colors, and the twoadjacent light emitting units 110 on the same row may also displaydifferent colors. Therefore, the light emitting units 110 with the samecolor may not be disposed collectively, such that the display panel 100may not easily have the phenomenon of inconsistent color distribution.

Moreover, in the embodiment, the first pixel circuits 120 are alldisposed on the (2N−1)^(th) row and the second pixel circuits 130 areall disposed on the (2N)^(th) row, where N is a positive integer. Thearrangement of each row in FIG. 4 is exemplified, the plurality of lightemitting units 110 on the (2N−1)^(th) row are sequentially the red lightemitting units 110 a, the white light emitting units 110 d, the greenlight emitting units 110 b and the blue light emitting units 110 c. Theplurality of light emitting units 110 on the (2N)^(th) row aresequentially the green light emitting units 110 b, the blue lightemitting units 110 c, the red light emitting units 110 a and the whitelight emitting units 110 d.

In terms of the arrangement of columns, the plurality of light emittingunits 110 on the (2M−1)^(th) column are sequentially the red lightemitting units 110 a and the green light emitting units 110 b, where thetwo colors are staggered and M is a positive integer. The plurality oflight emitting units 110 on the (2M)^(th) column are the white lightemitting units 110 d and the blue light emitting units 110 c, where thetwo colors are also staggered.

Referring to FIG. 4, in the embodiment, the light emitting units 110 onthe (2N−1)^(th) row and the (4M−3)^(th) column have the same color asthe light emitting units 110 on the (2N)^(th) row and the (4M−1)^(th)column. The light emitting units 110 on the (2N−1)^(th) row and the(4M−2)^(th) column have the same color as the light emitting units 110on the (2N)^(th) row and the (4M)^(th) column. Moreover, the lightemitting units 110 on the (2N)^(th) row and the (4M−3)^(th) column havethe same color as the light emitting units 110 on the (2N−1)^(th) rowand the (4M−1)^(th) column. The light emitting units 110 on the(2N)^(th) row and the (4M−2)^(th) column have the same color as thelight emitting units 110 on the (2N−1)^(th) row and the (4M)^(th)column. For example, when N=1 and M=1, the first row and the firstcolumn is the red light emitting unit 110 a, the second row and thethird column is also the red light emitting unit 110 a. Moreover, thefirst row and the second column is the white light emitting unit 110 d,the second row and the fourth column is also the white light emittingunit 110 d.

In the embodiment, for example, eight light emitting units 110 are takenas a group to form a repeat unit A, as shown in FIG. 4. The eight lightemitting units 110 are arranged into two rows and four columns, and theeight light emitting units 110 include the light emitting units 110 withfour different colors. Namely, each color in the group (the repeat unitA) has two light emitting units 110. The colors for the first row aresequentially the red light emitting unit 110 a, the white light emittingunit 110 d, the green light emitting unit 110 b and the blue lightemitting unit 110 c. The plurality of light emitting units 110 on thesecond row are sequentially the green light emitting unit 110 b, theblue light emitting unit 110 c, the red light emitting unit 110 a andthe white light emitting unit 110 d.

Specifically, the repeat unit A includes two sub units A1, wherein eachsub unit A1 includes four light emitting units 110. The four lightemitting units 110 are arranged into two rows and two columns, and thecolors of the four light emitting units 110 are not repeated. The twosame sub units A1 are arranged side by side to constitute a repeat unitA. Such repeat units A are incorporated with the corresponding datalines DL, scan lines SL and power lines PL to constitute the pixel arrayin the display panel 100.

According to the above descriptions, the plurality of light emittingunits 110 on the (2N−1)^(th) row are connected with the first pixelcircuits 120, and the plurality of light emitting units 110 on the(2N)^(th) row are connected with the second pixel circuits 130. Undersuch configuration manner, when the locations of photomasks have thedisplacement offset in the fabrication of the display panel 100, the redlight emitting unit 110 a, the white light emitting unit 110 d, thegreen light emitting unit 110 b and the blue light emitting unit 110 con the first row may have the compensation effect with the red lightemitting unit 110 a, the white light emitting unit 110 d, the greenlight emitting unit 110 b and the blue light emitting unit 110 c on thesecond row.

In addition, in the first embodiment, the scan lines SL connected to thefirst pixel circuits 120 on the (2N−1)^(th) row and the second pixelcircuits 130 on the (2N)^(th) row may have the same scan signal. FIG. 1and FIG. 4 are exemplified that the scan line SL connected to the firstpixel circuits 120 on the (2N−1)^(th) row and the scan line SL connectedto the second pixel circuits 130 on the (2N)^(th) row may be connectedwith each other. Therefore, the first pixel circuits 120 on the(2N−1)^(th) row and the second pixel circuits 130 on the (2N)^(th) rowmay be driven by the same scan signal.

Moreover, the light emitting units 110 on the (2N−1)^(th) row and thelight emitting units 110 on the (2N)^(th) row, for example, areconnected to different data line DL. In the first embodiment, the lightemitting units 110 on the (2N−1)^(th) row and the (4M−3)^(th),(4M−2)^(th) columns, and the light emitting units 110 on the (2N)^(th)row and the (4M−1)^(th), (4M)^(th) columns, for example, are allconnected to the odd data lines DL, while the light emitting units 110on the (2N−1)^(th) row and the (4M−1)^(th), (4M)^(th) columns, and thelight emitting units 110 on the (2N) row and the (4M−3)^(th),(4M−2)^(th) columns are all connected to the even data lines DL.

In this way, referring to FIG. 4, one of the sub units A1 in the repeatunit A composed by a group of eight light emitting units 110 may beelectrically connected to the data lines DL1, DL2, DL3 and DL4. To bespecific, the data lines DL1, DL2, DL3 and DL4 may be selectively andrespectively connected to the red light emitting units 110 a, the greenlight emitting units 110 b, the blue light emitting units 110 c and thewhite light emitting units 110 d. In other words, the (4M−3)^(th) dataline DL is configured to transmit the red signal, the (4M−2)^(th) dataline DL is configured to transmit the green signal, the (4M−1)^(th) dataline DL is configured to transmit the white signal and the (4M)^(th)data line DL is configured to transmit the blue signal. However, theinvention is not limited thereto.

It should be noted that, the arrangement order of the red light emittingunits 110 a, the green light emitting units 110 b, the blue lightemitting units 110 c and the white light emitting units 110 d in theembodiment may be not limited thereto. Although the red light emittingunit 110 a is on the first row and the first column, the green lightemitting unit 110 b is on the second row and the first column, the whitelight emitting unit 110 d is on the first row and the second column andthe blue light emitting unit 110 c is on the second row and the secondcolumn in the sub unit A1, the arrangement order of each color may beexchanged. For example, the green light emitting unit 110 b is changedonto the first row and the first column, the white light emitting unit110 d is changed onto the second row and the first column, the red lightemitting unit 110 a is changed onto the first row and the second column,and the blue light emitting unit 110 c is changed onto the second rowand the second column.

FIG. 5 is a schematic top view illustrating a display panel according toa second embodiment of the invention. Referring to FIG. 5, the secondembodiment is substantially similar to the first embodiment. The maindifference between the two embodiments lies in that the first pixelcircuit 220 and the second pixel circuit 230 on the two adjacent rowsare connected to the same scan line SL, in the second embodiment.

Since the first pixel circuit 220 and the second pixel circuit 230 onthe two adjacent rows are shared the same scan line SL, the thirdterminal 222 c of the first control transistor 222 in the first pixelcircuit 220 and the third terminal 232 c of the second controltransistor 232 in the second pixel circuit 230 both are connected to thesame scan line SL. Therefore, in order to incorporate with the locationof the scan line SL, in the second embodiment, the arrangement of thefirst driving transistor 221 and the first control transistor 222 in thepixel circuit 220 and the second driving transistor 231 and the secondcontrol transistor 232 in the pixel circuit 230, may be different fromthe first embodiment.

Here, the definition of the first direction D2 is the same as the firstembodiment, which is the main data transmission direction that the firstcontrol transistor 122 in the first pixel circuit 220 transmits the datafrom the data lines DL. Referring to FIG. 5, in the embodiment, theforward direction of the first direction D2 is defined as the firstterminal 222 a is relatively located below the second terminal 222 b andthe first terminal 232 a is relatively located above the second terminal232 b when the direction directs from the bottom to the top.

Accordingly, it is the same as the first embodiment described above thatduring the manufacturing process, when the second terminal 222 b of thefirst control transistor 222 is deviated from a predetermined locationtowards the forward direction of the first direction D2 in relative tothe third terminal 222 c, the second terminal 232 b of the secondcontrol transistor 232 is also deviated from a predetermined locationtowards the forward direction of the first direction D2 in relative tothe third terminal 232 c. Therefore, when the first control transistor222 and the second control transistor 232 are disposed in the manner asdescribed in the embodiment and an offset is generated in the displaypanel 200, the compensation effect similar to the first embodiment maybe achieved.

FIG. 6 is a layout diagram illustrating a display panel in FIG. 5.Referring to FIG. 6, to be specific, the second embodiment is the sameas the first embodiment, which is exemplified by the light emittingunits 210 appearing in red, green, blue and white four different colors.In other words, the light emitting units 210 including the red lightemitting units 210 a, the green light emitting units 210 b, the bluelight emitting units 210 c, and the white light emitting units 210 d,are exemplified to describe herein. Certainly, it is the same as thefirst embodiment described above, where the colors of the light emittingunits 210 are not limited to the combination of red, green, blue andwhite, it is possible to have combinations of other colors.

Similarly, in the second embodiment, the organic light emitting units210 with the same color are designed as that some parts are connected tothe first pixel circuits 220, while other parts are connected to thesecond pixel circuits 230. As described in the aforementionedembodiment, the arrangements of the first terminal 222 a and the secondterminal 222 b of the first control transistor 222 and the firstterminal 232 a and the second terminal 232 b of the second controltransistor 232 on the first direction D2 are incorporated to compensatethe parasitic capacitance variation caused by the displacement offset ofphotomasks in the fabrication.

In addition, a repeat unit B is formed by taking eight light emittingunits 210 from the light emitting units 210 in the display panel 200 asa group, and the repeat units B are repeatedly arranged. Furthermore, arepeat unit B is constituted by arranging the two same sub units B1 sideby side, wherein the color combination and the arrangement are the sameas the first embodiment, and thus the detailed description thereof areomitted hereby. It should be noted that, the arrangement of the lightemitting units 210 a, 210 b, 210 c and 210 d with different colors in asub unit B1 is utilized as an example to describe the embodiment, andthe designer may modify the arrangement of the light emitting unitsaccording to the actual situation.

Here, it is the same as the first embodiment, where in each of the subunits B1 having four light emitting units 210, the red light emittingunit 210 a is electrically connected to the data line DL1, the greenlight emitting unit 210 b is electrically connected to the data lineDL2, the blue light emitting unit 210 c is electrically connected to thedata line DL4, and the white light emitting unit 210 d is electricallyconnected to the data line DL3. Therefore, the signal transmissionmethod is the same as the first embodiment.

FIG. 7 is a schematic top view illustrating a display panel according toa third embodiment of the invention. Referring to FIG. 7, the thirdembodiment is substantially similar to the first embodiment.

However, in thethird embodiment, the light emitting units 310 on the (2N−1)^(th) roware connected to the odd data lines DL and the light emitting units 310on the (2N)^(th) row are connected to the even data lines DL. Therefore,in order for the red light emitting units 310 a to be electricallyconnected to the data line DL1, the green light emitting units 310 b areelectrically connected to the data line DL2, the white light emittingunits 310 d are electrically connected to the data line DL3 and the bluelight emitting units 310 c are electrically connected to the data lineDL4 in a repeat unit C, where the arrangement of the data lines DL isdifferent from the aforementioned embodiments.

Certainly, the signal transmission for the data lines of theembodiment is different from the first embodiment and the secondembodiment as described above, but the effect of compensating with eachother between the light emitting units 310 with the same color may stillbe implemented when the displacement offset of photomasks is generatedin the fabrication of the display panel 300.

Under the circumstances that thelight emitting units are capable of appearing in the three colors ofred, green and blue, there are also other arrangements, other than thearrangement in the fourth embodiment. Referring to FIG. 10, the lightemitting units 510 on the (2N−1)^(th) row and the (4M−3)^(th) columnhave the same color as the light emitting units 510 on the (2N)^(th) rowand the (4M−2)^(th) column, while the light emitting units 510 on the(2N−1)^(th) row and the (4M−2)^(th) column have the same color as thelight emitting units 510 on the (2N)^(th) row and the (4M−1)^(th)column, where M is a positive integer.

As illustrated in FIG. 10, the light emitting units 510 on the first roware arranged in the order of the red light emitting units 510 a, thegreen light emitting units 510 b and the blue light emitting units 510c. The light emitting units 510 on the second row are arranged in theorder of the blue light emitting units 510 c, the red light emittingunits 510 a, the green light emitting units 510 b, the blue lightemitting units 510 c, the red light emitting units 510 a, the greenlight emitting units 510 b . . . and so on.

Referring to FIG. 1 through FIG. 3, the second terminal 123 b of thefirst storage capacitor 123 is connected to the second terminal 121 b ofthe first driving transistor 121 in FIG. 2, and the second terminal 133b of the second storage capacitor 133 is connected to the secondterminal 131 b of the second driving transistor 131 in FIG. 3. In otherwords, the aforementioned embodiments are exemplified by thesemiconductor layer of the transistor that is an N-type semiconductor todescribe herein. Certainly, the invention is not limited thereto.

FIG. 11 is another driving circuit diagram for a first pixel circuit.Referring to FIG. 11, in the driving circuit illustrated in FIG. 11, thesemiconductor layer of the transistor is a P-type semiconductor, and thesecond terminal 623 b of the first storage capacitor 623 is connected tothe first terminal 621 a of the first driving transistor 621.

In this way, when a photomask occurs an offset onthe first direction in the manufacturing process, the deviated locationsof the first terminal and second terminal of the first controltransistor in relative to the location of the third terminal of thefirst control transistor may compensate the deviated locations of thefirst terminal and second terminal of the second control transistor inrelative to the location of the third terminal of the second controltransistor. Therefore, the parasitic capacitance variations aregenerated in the two control transistors (that is due to the photomaskoffset in the manufacturing process), where the parasitic capacitancevariation of one control transistor is increased and the parasiticcapacitance variation of another control transistor is decreased,thereby compensating with each other to improve the display quality ofthe display panel.

In addition, in the display panel of the invention, the arrangement ofthe light emitting diodes and the corresponding scan lines and datalines have a variety of different configurations and connection methods,such that the invention has the superior design flexibility on theactual applications. Moreover, the concept of the first controltransistor and the second control transistor in the invention may beapplied on a variety of different driving circuit designs, therefore,the invention has more extensive applicability.
